The B7 Sigma is perfectly suited for those users who want to dig deeper and work at heights more efficiently. It is ideal for jobs in densely populated areas and restricted urban sites due to its innovative Σ boom.The boom is a three piece offset one which offers many benefits compared to your standard boom:

Increased dig depth

Reduced layering at the bottom of trench

Increased productivity and vehicle rotation when loading trucks

Second part of the boom does not strike the left hand shoring plate when offset in a narrow trench

High efficiency working at height

A further big benefit and selling point of this excavator is it's ability to completely rotate (including upper frame and equipment) within the width of the tracks. Meaning however tight the space your machine is in it will be able to rotate fully 360°

These advantages combined make this machine ideally suited to the demolition industry, in fact at the 2015 Demolition Expo it was showcased within the Demolition Innovation category. Further reasons why the B7 Sigma is so suited to Demolition are shown below.
